Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Intel Iris Pro Graphics 5200 Mobile are very slightly better than the Nvidia GeForce GT 740M.
The GeForce GT 740M has a 410 MHz higher core clock speed and 24 more Texture Mapping Units than the Pro Graphics. This results in the GeForce GT 740M providing 22.7 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The GeForce GT 740M has a 410 MHz higher core clock speed and 12 more Render Output Units than the Pro Graphics. This results in the GeForce GT 740M providing 11.4 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.
The Pro Graphics was released less than a year after the GeForce GT 740M, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GeForce GT 740M has 2048 MB video memory, but the Pro Graphics does not have an entry, so the two GPUs cannot be reliably compared in this area.
The Iris Pro Graphics 5200 Mobile has 160 Shader Processing Units and the GeForce GT 740M has 384. However, the actual shader performance of the Pro Graphics is 314 and the actual shader performance of the GeForce GT 740M is 311. The Pro Graphics having 3 better shader performance is not particularly notable, as altogether the GeForce GT 740M performs better when taking into account other relevant data.
The Pro Graphics transistor size technology is 6 nm (nanometers) smaller than the GeForce GT 740M. This means that the Pro Graphics is expected to run very slightly cooler and achieve higher clock frequencies than the GeForce GT 740M. As they exhibit similar graphical performance, the Pro Graphics should consume less power than the GeForce GT 740M.
The Iris Pro Graphics 5200 Mobile requires 28 Watts to run and the GeForce GT 740M requires 33 Watts. The GeForce GT 740M requires 5 Watts more than the Pro Graphics to run. The difference is not significant enough for the GeForce GT 740M to have a noticeably larger impact on your yearly electricity bills than the Pro Graphics.

|Mini Review||Iris Pro Graphics 5200 Mobile are found in some of the 2013 Haswell mobile processors. |
They feature 40 Execution Units (160 Shader Processing Units), 8 TMUs and 4 ROPs. They share system memory and so the memory channel and speed will depend on the users configuration. The best possible combination is a dual-channel bus-width with an operating memory clock of 800MHz.
Its central unit and turbo frequency also depend on the CPU its embedded but it ranges from 400MHz to 1300MHz.
Compared to Iris Graphics 5100 Mobile, they offer an additional eDRAM cache of 128MB and so might offer performance identical to a dedicated GeForce GT 640M or a Radeon HD 7730M.
|GeForce GT 740M is a middle-class mobile graphics card based on the 28nm, Kepler architecture. |
It's based on the Kepler GK107 Core and offers 384 Shader Processing Units, 32 TMUs and 16 ROPs, on a 128-bit memory interface of DDR3. The central unit runs at 810MHz (890MHz in Turbo Mode) and the memory clock operates at up to 900MHz.
Its performance is therefore similar (though slower) to the DDR3 Variant of previous GeForce GT 650M and so most modern games will run at medium or high settings. Its power consumption should be lower, thanks to the power optimizations.
This Graphics Card needs to be paired with an average Quad Core CPU and can only achieve fluent frame rates at 1366x768.
